These tasks are normally carried out by service providers such as architects, planners, building companies and tradespeople. In addition, lawyers (e.g for planning processes, rent and construction law), surveyors (amongst other things for fire protection and structural analysis), banks for financing and accountants for tax issues are necessary.

These service providers not only need to be coordinated but also their activities controlled with a view to necessity and budget as well as keeping to deadlines. Here, two main aspects must always be considered: management of commercial effectiveness, budgetary and deadline controls as well as technical construction management.
